SYSTEM OF DISTRIBUTION.

Specification of Letters Patent.

Patented A11 6, 1918.

Application filed July 6, 1916. Serial No. 107,805.

To all whom it may concern:

Be it known. that 1, JOHN A. Burns, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Systems of Distribution, of which the following is a specification.

My invention relates to an improved method of storing surplus energy at certain definite points along a line in order that it may be utilized at these points for any desired purpose.

My invention relates particularly to systems of that class which employ two or more metallic conductors or line wires from station to station such as used for telephone circuits, selector circuits or any other multiple wire circuits and consists in so disposing in said circuits, electric storage devices that they will effectually store excess energy imposed upon the line in such a manner that the excess energy may be utilized at definite local points without interfering with the operation of the line circuits.

It can be seen that my invention is capable of a very wide range of application and may be utilized in a great number of ways, and

I have herein shown and described a few of the possible modifications of my invention. It has been found in a number of different instances such as in the use of telephones,

railroad signals, selectors and the like, that it is very desirable to have local sources of direct current energy at the various stations.

Up to the present time this has entailed very considerable expense in the maintenance of either dry cells 'or storage batteries and has also given a great amount of trouble on account of variation in the voltage at the various sources. y

My invention overcomes all the above enumerated troubles, while it still retains the advantages of the use of local batteries and therefore, my system may be installed over any extent of line without the trouble and expense of maintenance necessary with a local battery installation.

Other and further objects and advantages will be seen by reading and considering the following description taken in connection with the accompanying drawings forming part of this specification, and in which is described and represented diagrammatically some of the possible embodiments of my invention.

Figure 1. is a wiring diagram of a selector telephone system employing my invention and also shows how a railroad signal might be supplied with energy from the same source.

Fig. 2. shows my invention applied to an individual simplex telephone circuit with imposed telegraph and shows how it is possible to employ the stored energy at a way station for the operation of any desired circuit.

Referring to Fig. 1. I show a selector controlling circuit consisting of a sending device,-arranged to open and close contact 2 to send the-necessary electrical impulses over the line from battery 3 through retardation coils l and 5, line wire 6,'through selectors 7, 8, 9, and 10 in multiple, line wire 11, retardatioircoils 12 and 18, contact 2 to bat tery. The selectors 7, 8, 9, and 10 are located at the various way stations along the line of communication and it can be seen that by sending a suitable sequence of impulses along the line by means of sending device 1, any one of these selectors may be selectively operated to control a local circuit.

I have shown selector 7 diagrammatically, arranged to operate a contact lt to eontrol a call bell 15 and ring the same from a local source of energy hereinafter more fully described.

In order to maintain local sources of energy to operate the various devices at the Way stations and also operate signal mechanisms or any other devices along the route, I provide storage batteries 16, 17 18, 19 and 20 connected in series with the line wires 6 and will divide and pass through the linewires 6 and 11 in multiple, thereby keeping all the storage devices in series with these lines charged, passing through wire 27 to ground and back to the generator. It is obvious that this ground return may be replaced by a wire return where desired. Telephone trans- ,mitters 31 are shown at the way stations arranged to utilize the energy stored in the way station batteries by being connected around thebattery by means of wires 28,

through the primary windings 29 of the telephone transformers, wire 30, transmitters 31, wires 32 to the other side of their respective batteries. The secondary winding 33 of said telephone transformers are bridged across the lines by means of wires 34 through secondary 33, wires 35, telephone receivers 36, condensers 37, to opposite line, in the well known manner.

Storage battery 19 in line wire 11 is arranged to supply energy to a railroad signal 38 of any Well known type the circuit being from one side of battery through wire 39 contact 40 of well known track relay 41 wire 42 to signal 38 and thence through wire 43 to opposite side of battery 19.

The operation of the circuits is as follows:

Generator 26 is continuously in operation and is of such a voltage and capacity that it will supply energy slightly in excess of the consumption of energy from all the local batteries 16, 17, 18, 19 and 20 in the multiple circuit, and it will, therefore, keep all these batteries charged to their full capacity. Upon the operation of the sending device 1 to give a definite number of electrical impulses over the lines 6 and 11, to operate say selector 7, the selector 7 will operate and close its contact 14. This will close a local circuit from battery 18 through wire 44, selector contact 14; wire 45, bell 15, wire 46 back to battery and thereby ring the bell 15 for a given period or until the despatcher releases selector 7 according to the type of selector used. The man thus called will then take his telephone also operated with the energy supplied by battery 18 and talk over the line in the usual manner.

It can be seen that the line circuits 6 and 11 being in multiple may be so balanced that the charging current from the generator 26 will have no effect upon the instruments bridged across the line and in the event of a temporary failure of the generator 26, all of the batteries in the circuit, on account of being fully charged will continue to be operative for a considerable period during the repair of the generator 26.

hen the generator 26 is again started the batteries will immediately start to build up to their full charge as the current supplied by the generator is slightly in excess of. the current consumed by all of the local circuits along the line.

Fig. 2 is a modification of the circuits shown in Fig. 1 and shows a condition where the telephone circuits are simpleXed and the selectors are controlled upon an independent circuit, a telegraph circuit also being superimposed upon the telephone circuit.

A generator 26, one side of which is grounded is employed in the same way as in Fig. 1, the current passing through a polarized relay 47 contact of polarized relay 48,

wire 45 normally closed telegraph key 49 telegraph relay 50, battery 51, two sides 52 and 53 of telephone circuits, battery 54, telegraph key 55, telegraph relay 56, two sides 57 and 58 of telephone circuit, battery 59, two sides of telephone circuit 60 and 61, battery 62, telegraph relay 63, 1 normally closed telegraph key 64 wire 65, contact of polarized relay 66 polarized relay 67 to ground 68 and back to generator 65, thereby keeping all of the storage batteries 51, 54, 59 and 62 charged as in Fig. 1.

In this instance the current used to charge the storage batteries, is also interrupted to operate the telegraph instruments, the generator 26 being of such a capacity that. it will supply sufficient energy to maintain the storage batteries charged irrespective of the interruptions in the circuit caused by the operation of the telegraph apparatus. The telephone transmitters are bridged across the batteries as shown at battery 59 by means of wire 69 from one side of battery, transmitter 70, wire 71, primary of telephone coil 72, wire 73 back to battery 59. By means of suitable jacks 74 and plugs 75 the operator may talk over any circuit that he desires.

I have shown at battery 54 how a local telegraph circuit may be operated by the storage battery and also a selector bell circuit which is provided with the well known answer back coils 76. The local telegraph circuit is from battery 54, through wire 77 sounder 78 wire 79 contact 80 of telegraph relay 56, wire 81 to battery; the local bell circuit is also bridged across the same battery 54 through wire 82 bell 83 wire 84 answer back coils 76, selector contact 85, wire 86, back to battery. Upon the operation of the bell 83 an inductive kick will be created in the selector coils 87 which will be heard in the despatchers telephone bridged across the selector line and thereby indicate to the despatcher that the bell has operated.

The polarized relays 47 and 67 are inserted to automatically disconnect the line from ground in the event of failure of the generator, and thereby prevent the unnecessary back discharge of the storage batteries in the circuit.
